SPECIFICATION forming part of Letters Patent No. 696,608, dated April 1,1902.

Application filed April 4:, 1898.

T0 @ZZ whom, it may concern:

Beit known that I, WARREN l-I. TAYLOR, a citizen of the United States,and a resident of Stamford, in the county of Fairfield and State ofConnecticut, (whose post-office address is Stamford, in the county ofFairfield and State of Connecticut,) have invented certain new anduseful Improvements in Lock-Hubs, of which the following is aspecification.

My present invention relates to the construction of lock-hubs for thelatch-operating arm.

The features of my said invention are a trunnioned hub having an angularspindleopening and a latch-operating arm connected with the hub throughthe medium of a ring which seats upon a reduced neck formed on the hub.The hub is made in two sections, each of which is provided with aportion of the reduced neck, over which the ring of the latch-operatingarm iits, while said ring is provided with an inwardly-projectingportion which the ends of the hub-section abut and through which isformed an angular spindleopening which is a continuation of the angularspindle-opening in the hub-sections.

The invention will be fully understood upon reference to theaccompanying drawings, in Which- Figure l is a longitudinal sectionalview of the hub, and Fig. l is an end View.

I form the hub 1 with a reduced neck 2 and with the usual trunnions 3,which engage in the bearings in the lock-casing (not shown) in amannercomlnon to locks of this character. A latch-operating arm 4 isprovided with a ring 5, which fits over the reduced neck of the hub,which is divided in the plane of the Serial No. 676,426. (No model.)

ring into sections, each of which is formed with a portion of thereduced neck.

The ring` 5 holds the two sections of the hub in alinement and isprovided with an inwardly-projecting portion which is gripped betweenthe hub-sectionswhen they are confined between the two plates of thecasing, and the inwardly-projecting portion is provided with an angularopening 7 to receive the knob-spindle.

Having thus described my invention, the following is what I claim as newtherein and desire to secure by Letters Patent:

1. The combination of a h ub formed with both trunnions, a reduced neck,and an angular spindle-opening, and a latch-operating arm having a ringfitting around the reduced neck, so that the trunnions project beyondit; the hub being divided in the plane of the ringso that the latter isgripped between the parts of the hub when said parts are held togetherby the lock-casing, when the hub is in use.

2. The combination of a hub, having trunnions, and a reduced neck formedthereon, and an angular spindle-opening formed therein, the hub beingdivided through the reduced neck to form a neck portion on each part ofthe hub; and a latch-operating arm having a ring tting around bothportions of the reduced neck, and having a central portion 6 introducedbetween the hub parts and formed with a spindle-opening.
